Abstract
The use of the sub-terahertz (THz) band is a promising candidate to cope with the ever-increasing traffic in wireless access. Since the transmission range in the sub-THz band is reduced due to its large propagation loss, received power needs to be enhanced using beamforming technologies. The authors focused on Bessel beams (BBs), which show high received power performance up to a certain distance, and evaluated their performance experimentally. The experiments were carried out at 140 GHz using small (15 cm diameter) dielectric and metasurface lenses. When using these small lenses, received power was increased by up to 15 and 11 dB, respectively, and the received power for distances up to 70 cm was greater than that of a conventional collimated beam.
